Fox News is projecting that Hillary Clinton will clinch the Democratic presidential nomination after a win in the New Jersey Democratic party.

With the win, Clinton becomes the first woman in American history to top the ticket of a major political party.

Tuesday’s win comes a day after The Associated Press reported that Clinton had captured commitments from the number of delegates needed to become the Democrats' presumptive nominee due to a decisive weekend victory in Puerto Rico and a burst of last-minute support from superdelegates, according to the news agency.

While it is too early to say whether Clinton will win the state of New Jersey outright, Fox News did project she will win enough of the state’s delegates to easily surpass the 2,383 needed to clinch the nomination.

Due to the fact that Clinton’s victory is based in part on the support of superdelegates, who do not technically vote for a nominee until the Democratic National Convention next month, her rival Bernie Sanders has vowed to stay in the race in hopes of convincing enough superdelegates to abandon Clinton and support him instead.

It remains to be seen whether Sanders will make good on that threat – the decision may rest in part on whether he wins the marquee primary in California, where polls close late Tuesday night, noted Fox News.

New Jersey and California were among six states voting Tuesday – alongside Montana, New Mexico, North Dakota and South Dakota.

Even before Tuesday’s contests, both parties effectively had their presumptive nominees. Trump clinched the nomination last month as late support from unbound delegates put him over the top, and his remaining rivals suspended their campaigns.

Trump was also projected to win New Jersey, receiving 83.4% of the votes amounting to 51 delegates, according to an Associated Press tally.
